Description
Want an AR-15 trigger that suffers no creep, take-up, or over-travel? Looking for the easiest-to-install LPK? How about the most affordable parts kit possible? This mil-spec AR-15 LPK comes in at a great price with machining and performance that feels match-grade.
Polished for Performance
Inside this kit, you’ll find a disconnector, hammer hook, and sear that were laser-cut and polished to break as clean as glass at exactly 4.5 pounds.
